A new study discovered that high-powered MRI scans may cause the mercury in dental fillings to leak, leading to mercury poisoning. Should people with metal dental fillings consult their dentist on a possible replacement?

Mercury’s crust is found to be thinner and denser than previously thought. It is also interesting that Mercury’s core is larger than its mantle and crust, although scientists have not reconciled theories to prove its cause.

Researchers found the world's largest reserve of natural mercury hidden underneath Arctic permafrost. The discovery, however, comes with the warning that the toxic element may be released if the permafrost thaws due to climate change.

According to a new study by Rutgers University, climate change and high precipitation would trigger runoff into oceans and pump huge levels of mercury into oceanic creatures including fish and zooplanktons and harm the whole food chain.

A complete guide on star gazing shows everything needed to catch astronomical sights in 2017. It will also list the best constellations each planet will occupy during the year in broad details covering conjunctions, oppositions, and elongations.

Mercury is no larger than the Earth’s moon and it’s still shrinking! Researchers came to this conclusion after discovering small fault scarps on the planet, which also shed light on Mercury’s active tectonic activity.

NASA has released new digital models that show various aspects of Mercury. These include the amount of volcanic activity on the planet as well as its geological history. Data for these maps were gathered by the MESSENGER spacecraft.

Studying the planet Mercury is quite difficult because of its proximity to the sun, but MESSENGER's past mission has helped scientists find new data from the planet. One very puzzling aspect of the planet is its very dark surface.

A new, affordable material was found to be capable of helping against mercury pollution and taking mercury out of water and soil. It was obtained from two industrial waste materials: sulphur and limonene, which is found primarily in orange peels.

Scientists have found a way to eliminate water pollution caused by mercury dumped by industrial processes. The ocean cleaning agents function the same way real corals do, absorbing mercury, but are not prone to dying because they are made of synthetic materials that mimic real corals’ features.

Images and data from NASA's MESSENGER spacecraft suggest that the strength of Mercury's magnetic field once rivaled that of the Earth's. Mercury and Earth are the only planets in the solar system that have magnetic fields produced by their liquid metal core.

The concentration of mercury found in the Hawaiian yellowfin tuna has increased by at least 3.8 percent per year. Researchers sounded the alarm, saying that the toxic substance in fish is increasing all the time.

Pregnant women tend to avoid eating fish because of mercury contamination but researchers found evidence that fatty acids in fish does not just help with brain development. They can also counteract the potential toxic effects of mercury.

NASA's MESSENGER orbit will run out of fuel by March 2015. To commemorate the success of the mission, scientists have launched a competition that gives ordinary people the chance to name five craters in Mercury. Here are the rules.
